Both the Honeycomb devices are set to "normal" and NOT slew. So, I don't understand your explanation
I figured out you didn't understand. There's no such thing as a "joystick set to normal", opposed to a "joystick set to slew". The joystick is not set to anything.
It's the SIMULATOR that has its Controls setting divided between "Normal" and "Slew" flight modes, and to either of these modes, it might have automatically assigned some of your existing joystick Axes to various event.
So, when I said you need to be sure you are in the Slew flight mode, I simply meant that, the Axes event you need to REMOVE, should be the ones for the Slew mode, not the ones on Normal flight, otherwise you might end up removing event assigned to Axes you need in *ACTUAL* flight, which is not what you want to do, and it's not what will fix your problem, because your problem is that, when GSX puts the airplane momentarily in Slew mode, the uncalibrated Axes (one that is assigned in *SLEW* mode, not normal flight) is making the airplane spinning out of control.
If you still don't understand, check this video, I linked it exactly where it goes in the Control menu to set Slew mode events:
&t=58s
The only difference is that when he says "go to Buttons and Keys, select Slew mode", in YOUR case should be "go to Controls Axes, select Slew mode".
Be sure you check all your joystick devices, which should be visible in the "Controller Type" list, and be sure they don't have any Axes assigned IN SLEW MODE, that is AFTER you select Slew mode from the "Control Axes" tab of the Controls settings page.
I really don't know how to explain it any better than this. Note that, this is BASIC FSX functionality we are discussing here, nothing related to GSX in any way.
